Description

Technical Field

[0001] The invention relates to the technical field of barcode recognition, and in particular to a self-service book borrowing device for barcode recognition. Background Art

[0002] With the continuous advancement of information technology, barcode recognition technology has gradually matured and is widely used in various fields. In terms of book management, barcode recognition makes it possible to realize automated borrowing. Self-service book borrowing equipment has emerged, aiming to use barcode recognition technology to allow readers to complete book borrowing and returning operations by themselves without relying too much on the assistance of library staff.

[0003] According to the Chinese patent with the announcement number: CN112419608A, a barcode recognition self-service book borrowing device is disclosed, including a device body, a display stand, a book outlet and a control panel. A rectangular groove is opened on the surface of the control panel, and barcode scanners are fixedly installed on the upper and lower sides of the rectangular groove. Transparent protective covers are fixedly provided on the upper and lower sides of the rectangular groove and located outside the barcode scanner. A cleaning mechanism for wiping the surfaces of the two transparent protective covers is provided at the bottom of the rectangular groove. The present invention adopts two barcode scanners, and at the same time, the barcode scanner's recognition accuracy for the barcode is guaranteed, thereby improving the efficiency of borrowing books by barcode recognition.

[0004] In the above scheme, it was found during use that when the device was in use, the barcode scanner could not move according to the barcode attached to the book. For books of different sizes and shapes or when the position of the barcode on the book was inconvenient for scanning, it was necessary to adjust the position and angle of the book laboriously to adapt to the barcode scanner, which increased the difficulty and time cost of the borrowing operation. This inconvenience would be more obvious, especially when the reader was in a hurry to borrow books or had multiple books in both hands, and it would easily make the reader feel irritated. At the same time, during the peak borrowing period, each reader would have to spend extra time to adjust the position of the book to complete the scan, which would cause the movement speed of the entire borrowing team to slow down. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a barcode recognition self-service book borrowing device, which solves the problems mentioned in the background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A barcode-recognized self-service book borrowing device comprises: a main body, four anti-skid pads are fixedly installed on the bottom of the main body, a placement plate is fixedly installed on one side of the main body, a rectangular groove is opened on one side of the main body, and slide grooves are respectively opened on both sides of the interior of the rectangular groove; a movable adjustment component is arranged inside the rectangular groove and used for adjusting the position. When in use, the anti-skid pad increases the friction with the placement plane to ensure that the device will not slide or shift due to external force during use. The reader places the book to be borrowed or returned on the placement plate fixedly installed on one side of the main body, and the movable adjustment component starts to work. It is arranged inside the rectangular groove and uses the slide grooves opened on both sides of the interior of the rectangular groove to achieve position adjustment.

[0008] By adopting the above technical solution, a main body is set up as the basic framework of the entire self-service book borrowing device, providing a platform for installation and bearing for other components, ensuring that various components work together on a stable structure, and the anti-skid pad effectively prevents the device from unnecessary sliding or displacement due to external force collision, operation vibration and other factors during use. The placement plate provides readers with an extremely convenient temporary book placement area, and the rectangular groove provides a specific installation and operation space for the mobile adjustment component and its related components. The slide groove cooperates with the rollers on the mobile block to form a guiding mechanism for the horizontal movement of the mobile block in the rectangular groove. The mobile adjustment component improves the flexibility and adaptability of the barcode scanner, and can automatically adapt to books of different sizes, shapes and barcode positions.

[0009] Preferably, the movable adjustment component includes: two movable blocks, the two movable blocks are arranged inside the rectangular groove, one side of the two movable blocks is respectively provided with a first installation groove, the inside of the two first installation grooves are respectively fixedly installed with a first drive motor, one end of the rotating shaft of the two first drive motors is respectively fixedly installed with a roller, and the roller movably sleeve is arranged inside the slide groove.

[0010] By adopting the above technical solution and setting a moving block, a stable installation foundation is provided for other related driving and transmission components. The first installation groove provides an installation space for the first drive motor. The first drive motor is the power source for the horizontal movement of the moving block. By driving the roller to rotate, the electrical energy is converted into mechanical energy, and the roller rolls in the slide groove, thereby driving the entire moving block to move horizontally along the direction of the slide groove. The roller and the slide groove cooperate closely to realize the smooth movement of the moving block in the horizontal direction.

[0011] Preferably, the movable adjustment component also includes: two second mounting grooves, the two second mounting grooves are respectively opened on one side of the two movable blocks, synchronous motors are respectively fixedly installed inside the two second mounting grooves, a screw rod is fixedly installed between the two synchronous motors, and two limit rods are fixedly installed between the two movable blocks.

[0012] By adopting the above technical solution, an installation position is provided for the synchronous motor through the second installation groove. The synchronous motor serves as a power device for driving the screw to rotate and can accurately control the rotation speed of the screw. When the synchronous motor drives the screw to rotate, the mounting block can move linearly along the axial direction of the screw. The limit rod restricts the mounting block to move linearly only along the direction of the limit rod, thereby preventing the mounting block from rotating or deviating due to the rotation of the screw.

[0013] Preferably, the movable adjustment component also includes: a mounting block, the mounting block is arranged between the two movable blocks, a first threaded hole is provided on one side of the mounting block, the first threaded hole is threadedly connected to the screw rod, two limit holes are provided on one side of the mounting block, the limit holes and the limit rod are movably mounted, and a barcode scanner is fixedly installed on the bottom of the mounting block.

[0014] By adopting the above technical solution, a mounting block is set as a mounting carrier for components such as a barcode scanner and an air pump. The first threaded hole cooperates with the lead screw. When the synchronous motor drives the lead screw to rotate, the mounting block converts the rotational motion of the lead screw into its own linear horizontal motion by virtue of the threaded connection between the first threaded hole and the lead screw. The limit hole and the limit rod work together to provide a stable and precise guide path for the horizontal movement of the mounting block. The barcode scanner uses optical scanning technology to read the barcode information on the book and converts it into a digital signal for transmission to the control system of the device.

[0015] Preferably, an air pump is fixedly mounted on the top of the mounting block, an air supply pipe is fixedly mounted on the air outlet of the air pump, a first bracket is fixedly mounted on one side of the mounting block, a first circular hole is opened on the top of the first bracket, and the air supply pipe is fixedly mounted inside the first circular hole.

[0016] By adopting the above technical solution, an air pump is set up as the power core of the jet cleaning system. Air is sucked in and compressed through operation to provide a stable source of airflow with a certain pressure for subsequent jet cleaning actions. The air supply pipe transmits the compressed air generated by the air pump to the L-shaped jet gun, and the first bracket provides a stable and precise installation support position for the air supply pipe.

[0017] Preferably, a second bracket is fixedly mounted on one side of the barcode scanner, a second circular hole is opened on the top of the second bracket, an L-shaped air jet gun is fixedly mounted inside the second circular hole, and the other end of the air supply pipe is fixedly mounted to the L-shaped air jet gun.

[0018] By adopting the above technical solution, a second bracket is set up for installing an L-shaped jet gun, and its jet end is accurately positioned near the barcode scanner and aimed at the scanning area. The L-shaped jet gun enables the ejected airflow to better cover the barcode scanner lens, remove dust on the barcode scanner lens, maintain the cleanliness of the scanning area, and improve the success rate of barcode recognition.

[0019] Preferably, third mounting grooves are respectively opened on both sides of the interior of the rectangular groove, and second drive motors are respectively fixedly installed inside the two third mounting grooves, and telescopic rods are respectively fixedly installed on one end of the rotating shafts of the two second drive motors, and U-shaped mounting frames are respectively fixedly installed on the telescopic ends of the two telescopic rods.

[0020] By adopting the above technical solution, by setting the third installation groove, providing installation space for the second drive motor, the second drive motor can control the rotation of the telescopic rod. When the barcode is placed on the bottom of the book, which is not conducive to conventional scanning, the second drive motor can drive the telescopic rod to rotate, thereby driving the U-shaped mounting frame and the clamped book to rotate, and rotating the barcode to the top and other positions that are convenient for the barcode scanner to scan, thereby reducing the complexity and tediousness of the borrowing operation. The telescopic rod can accurately change the distance between the two U-shaped mounting frames to adapt to the placement requirements of books of different sizes and thicknesses.

[0021] Preferably, two fourth mounting grooves are respectively provided on both sides of the interior of the two U-shaped mounting frames, third drive motors are respectively fixedly installed inside the eight fourth mounting grooves, a bidirectional threaded rod is fixedly installed between the two third drive motors, and two clamping plates are respectively arranged inside the two U-shaped mounting frames, two second threaded holes are respectively provided on the tops of the two clamping plates, and the second threaded holes are threadedly connected to the bidirectional threaded rod.

[0022] By adopting the above technical solution, a fourth mounting groove is set to provide an installation space for the third drive motor. The third drive motor converts electrical energy into mechanical energy by driving the bidirectional threaded rod to rotate, thereby providing power for the movement of the clamping plate. The bidirectional threaded rod drives the two clamping plates to move synchronously in opposite directions or opposite directions through a threaded connection. The movement distance of the clamping plate can be accurately adjusted to achieve precise adaptation to books of different thicknesses. The clamping plate can clamp and release the book under the drive of the third drive motor through a threaded connection with the bidirectional threaded rod, and can firmly fix the book to prevent the book from moving due to equipment vibration or other external forces during the scanning process, thereby ensuring that the barcode scanner can stably read the barcode information.

The limit hole and the limit rod work together to provide a stable and precise guide path for the horizontal movement of the mounting block. The barcode scanner uses optical scanning technology to read the barcode information on books.
